Audory: PDF to Audiobook

Import a PDF, EPUB, or text file and listen to it in a natural voice, with the words highlighting as they are read. Everything runs on your device, so your files never leave your phone and it all works offline. Pick a voice, set a sleep timer, and keep listening with the screen off. Add a soft background like rain or a campfire when you want to settle in. There is also a free library of public-domain classics to listen to right away.
